4. Setup and Installation
The Hormann HE 1 receiver is designed for straightforward integration with compatible Hormann gate and garage door operators. Follow these steps for proper installation:

- Disconnect Power: Before making any electrical connections, ensure the power supply to the Hormann gate or garage door operator is completely disconnected at the main circuit breaker.
- Mount the Receiver: Use the provided installation material (e.g., screws) to securely mount the receiver unit in the chosen location. The casing has pre-drilled holes for this purpose.
- Connect Wiring: The receiver comes with a 0.5-meter, 3-wire connection cable. Carefully connect these wires to the appropriate terminals on your Hormann gate or garage door operator.
- Refer to your specific Hormann operator's manual for the correct wiring diagram for a 24 V DC pulse input.
- Ensure correct polarity if specified by your operator. The receiver requires a 24 V DC supply.
- Secure Connections: Double-check all wire connections to ensure they are tight and secure. Loose connections can lead to intermittent operation or electrical hazards.
- Restore Power: Once all connections are verified and secure, restore power to the gate/garage door operator.
Note: This receiver is designed to work with Hormann gate/garage door operators that accept a 24 V DC pulse input for activation. Compatibility with other brands or systems is not guaranteed.
5. Operating Instructions
The Hormann HE 1 radio receiver acts as an interface between your Hormann 868 MHz remote control (not included) and your gate/garage door operator. Its function is to provide a brief 0.5-second pulse to the operator when a valid signal is received.
- Pairing Remote Control: Before operation, you must pair your Hormann 868 MHz remote control with the HE 1 receiver. The exact pairing procedure depends on your specific Hormann remote control and operator model.
- Typically, this involves pressing a programming button on the receiver or operator, followed by pressing a button on the remote control.
- Refer to the instruction manual of your Hormann remote control and/or garage door operator for detailed pairing instructions.
- Normal Operation: Once paired, pressing the programmed button on your Hormann 868 MHz remote control will send a signal to the HE 1 receiver. The receiver will then generate a 0.5-second pulse, which triggers the connected Hormann gate or garage door operator to perform its programmed action (e.g., open, close, stop).
- Signal Range: Ensure you are within the effective operating range of the receiver when attempting to activate the gate/door. Obstacles and interference can affect signal range.
6. Maintenance
The Hormann HE 1 radio receiver requires minimal maintenance to ensure long-term reliable operation.
- Cleaning: Periodically wipe the exterior of the receiver with a soft, dry cloth to remove dust. Do not use liquid cleaners, solvents, or abrasive materials.
- Inspection: Annually inspect the connection cable for any signs of wear, fraying, or damage. Ensure all electrical connections remain secure.
- Environment: Ensure the receiver remains in a dry environment. If the installation location becomes damp or wet, relocate the receiver to a suitable dry area.
- No User-Serviceable Parts: The receiver contains no user-serviceable parts. Do not attempt to open the casing.
